315 PM EDT TUE JUN 15 2004

.SHORT TERM...
STATIONARY FRONTAL BOUNDARY WAS LOCATED ACRS NRN IL...NRN IN...THEN
INTO NRN OHIO THIS AFTERNOON.  A VERY WARM...MOIST AIRMASS WAS
LOCATED SOUTH OF THIS BOUNDARY.  SHOWERS AND THUNDERSTORMS HAVE
ERUPTED DUE TO THE DAYTIME HEATING...RESULTING IN VERY HEAVY
RAINFALL ACRS PARTS OF THE CWFA.  THE NRN CWFA...ESPECIALLY ALONG
AND NORTH OF I-70...HAVE THE LOWEST FFG VALUES...WHICH ARE NEAR 1
INCH.  HAD CONTEMPLATED ABOUT ISSUING A FLOOD WATCH FOR THIS REGION
ONLY.  HOWEVER...WITH ETA MODEL DEPICTING NEARLY 2 INCHES OF
PRECIPITABLE WATER ACRS THE SOUTH TONIGHT INTO THE FIRST PART OF
WEDNESDAY...I HAVE NOW DECIDED TO PLACE A FLOOD WATCH FOR THE ENTIRE
REGION.  ETA MODEL SHOWS A VORT LOBE ROTATING NORTH ACRS THE CWFA
TONIGHT...THEN INTO THE LOWER GREAT LAKES BY WEDNESDAY AFTN.  AS A
RESULT...NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TONIGHT
INTO THE FIRST PART OF WEDNESDAY AS THIS FEATURE INTERACTS WITH A
WEAK LOW LVL JET.

FOR WEDNESDAY NIGHT...ANOTHER S/WV APCHES FROM THE WEST.  THE ETA IS
MUCH FASTER WITH THIS FEATURE THAN THE GFS.  HAVE OPTED FOR THE ETA
SOLUTION ATTM...WHICH BRINGS ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS WEDNESDAY NIGHT.

ON THURSDAY...COLD FRONTAL BOUNDARY APCHES THE REGION FROM THE NW.
THERE SHOULD BE A MINIMUM IN POPS THURSDAY AFTN BEFORE FRONT MOVES
THROUGH REGION THURSDAY NIGHT...BRINGING YET ANOTHER CHANCE OF
SHOWERS AND THUNDERSTORMS.

IN TERMS OF TEMPS...HAVE GONE A LITTLE WARMER ON LOWS TONIGHT
THROUGH THURSDAY NIGHT GIVEN HIGH DEWPOINTS.  FOR HIGHS...HAVE
TWEAK SLIGHTLY WARMER THAN THE MAV GUIDANCE THROUGH THE PERIOD.

&&

.LONG TERM...
BIGGEST CHALLENGE IS ATTEMPTING TO FIND AN EXTENDED DRY PERIOD FROM
THE EXCESSIVELY WET AND STORMY PATTERN THAT HAS BLANKETED THE OH VLY
SINCE ERLY MAY. MODELS HAVE HAD ALL SORTS OF TROUBLE RESOLVING S/WVS
ALONG THE STAGNANT FRNTL BNDRY...BUT HAVE HAD A COUPLE RUNS IN A ROW
NOW THAT ARE FINALLY KICKING FRNTL BNDRY SOUTH AND EAST OF FCST AREA
ON FRI.  12Z GFS SLOWING DOWN FROPA INTO FRI AFTN...BUT THIS REMAINS
SLOWEST OF ALL EXTENDED SOLNS.  HAVE GONE WITH LO CHC POPS SOUTH AND
EAST OF I-71 FRI MRNG...WITH DRY WX ACRS ENTIRE FCST AREA BY FRI
AFTN WITH SFC HI PRES BRIEFLY BUILDING IN.  BACK EDGE OF FRNTL BNDRY
THEN PROGGED TO RETURN NORTH SAT NIGHT INTO SUN AS SFC LO TRACKS
THRU LWR GRT LKS/OH VLY.  ALSO ATTEMPTED TO PLACE TIMING WITH THESE
FEATURES...NOT BRINGING PCPN CHANCE INTO REGION UNTIL SAT LATE
AFTN/EVNG.  KEEPING POPS NO HIGHER THAN 30 WITH UNCERTAINTY ATTM.

FRNTL BNDRY WILL PULL EAST OF REGION BY SUN AFTN WITH SFC HI PRES
RETURNING. 00Z GFS REMAINS MOST AMPLIFIED SOLN FOR SUN-TUES...DVLPG
EASTERN CONUS UPR TROF WITH STRONG SFC LO TRACKING THRU SRN CANADA.
WHILE THIS SOLN IS FAR LESS AMPLIFIED THAN 14/00Z GFS SOLN...STILL
FEEL THAT GFS LOOKS TOO AMPLIFIED.  THIS THINKING IS FURTHER
SUPPORTED AS ECMWF/UKMET BOTH REMAIN CONSISTENT IN INDCG MORE ZONAL
FLO PATTERN ERLY NEXT WEEK.  12Z GFS ALSO APPEARS TO SHOW LESS
AMPLIFICATION BEHIND SUN FROPA.  HAVE CONTINUED WITH PREV TREND FOR
WARMER/DRIER WX SUGGESTED BY ECMWF/UKMET SOLNS FROM SUN NIGHT THRU
TUES...WITH U70S/NEAR 80 FOR AFTN HIGHS AND U50S/NEAR 60 FOR LOWS.
